I've just purchased a Faderport 8. All is (generally) as expected, but I've run into one annoying issue that I can't seem to fix.
I purchased the FP8 largely to use the faders to control parameters in virtual instruments - in Kontakt or Spitfire Audio's native plug-in for example. I've discovered the best way to do this is to use the FP8 in midi mode. So far, so good, but . . .
To illustrate the issue - fader 1 is assigned to expression, fader 2 to dynamics and fader 3 to vibrato. The strange behaviour is that fader 1 tracks the movement of fader 3. For the life of me, I can't seem to de-link them (although fader 3 does not do what fader 1 does, fader 1 follows the movements of fader 3 if 3 is being used on its own or fader 1 moves to mirror the position of fader 3 once I let go of it).
This is not a critical issue. I can just ignore fader 1 and use the other 7, I suppose, but I've become intrigued as to why fader 1 acts in such an anomalous fashion. [At one point, I had mapped six of the faders. Fader 1 started following fader 5!]
I don't think this is a Logic Pro problem, but any assistance would be gratefully received.

Another odd fader 1 issue - while I'm on the subject - is that in MCU mode, pushing the Pan button causes all of the faders to act as pan controllers for their respective channels, except fader 1, which continues to address track volume. Ah, well . . .

And . . . I've just discovered that the fader 1 behaviour - in midi mode - only occurs once I've played a note on my midi controller (i.e., keyboard). The mystery deepens . . .
